Has anyone else had any issues with the downstream O2 sensor on their SVT? For some reason, mine only has about 1/8" clearance between the end of the sensor and the drive axle, and whenever I hit a bump that jars the exhaust system (it happens, this is Texas), it destroys the sensor. I'm not the original owner, and I'm thinking the previous owner changed the exhaust or something to change the placement of the cat. I've gone through about 4 sensors in the past 6 months. I searched the forums, but didn't find anything. I searched the forums to no avail, but if anyone has any pointers or tips I'd appreciate it. Thoughts?
